I love the title of this thread I am starting to focus more on the Couch to 5K conditioning, and have also discovered Brian McKensie's Crossfit Endurance website. He has a LOT of information/videos on proper body mechanics for beginning (and elite) runners, as well as cycling and swimming. I don't want to take on too much too soon and wind up with injuries because my posture is off or my body just isn't ready.
